The coverity checker detected a use-after-free error in
drivers/media/video/cpia2/cpia2_v4l.c::cpia2_close() (coverity
error #1281).
What happens is that we lock cam->busy_lock, then proceed to free
resources, and in the case of (--cam->open_count == 0) we finish off by
doing a kfree(cam) and then at the end of the function we do a
mutex_unlock(&cam->busy_lock) which will explode since it'll dereference
the free'd `cam' :
...
mutex_lock(&cam->busy_lock);
...
if (--cam->open_count == 0) {
...
if (!cam->present) {
video_unregister_device(dev);
kfree(cam);
}
}
mutex_unlock(&cam->busy_lock); <--- PROBLEM, cam no longer around.
...
Since this only happens in the case of open_count going down to zero I
don't see a problem with just releasing the mutex after unregistering the
device and just before the kfree(). In this case there is nothing around
that we can race against; we are in the release method, open_count is zero,
(!cam->present) and the device has just been unregistered, so letting go of
the mutex at this point looks safe to me.
Patch below to implement that solution.

In addition to adding a number of buttons to the current winfast definition,
it enables all the keys currently masked out with #ifdef 0.
It is supplied separately as it remaps two keys from the current definition,
The teletext button now sends KEY_TEXT instead of KEY_SUBTITLE, as that
keycode is used by the subtitle button.
KEY_BACK was changed to KEY_LAST to group it with KEY_NEXT.
Other then that the keys don't overlap, so this should support several

The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
always, before you could assign the static pointer directly, which was
dangerous.
